Google have today added 3D buildings to Google Maps in more cities around the world. The new cities include London, Paris, Barcelona, Stockholm, Singapore, Lisbon, Boulder, and 11 major cities in South Africa.

In Google Maps the 3D buildings look pretty cool but they really only come to life on Google Maps for mobile. On Google Maps for mobile you can rotate, tilt, and zoom in and out on the buildings.My guess is that at some point soon Google will look to implement the rotate and tilt views in Google Maps for the desktop.

The rotating buildings obviously make more sense on mobile maps where the orientation of the map can rotate to reflect your view. However this would be a great feature to be able to access via the Google Maps API. I could see this being a popular tool with many map developers.
